Answer:
The midpoint is ( 4 , - 2)
Step-by-step explanation:
The midpoint (M) of any two points
(x1 , y1) and ( x2 , y2) is written as
[tex]( \frac{x1 + x2}{2} \: \frac{y1 + y2}{2} )[/tex]
So the midpoint of C (1, -9) and D (7, 5 )
is
[tex]( \frac{1 + 7}{2} \: \: \frac{ - 9 + 5}{2} ) \\ \\ = ( \frac{8}{2} \: \: - \frac{4}{2} )[/tex]
Which is
( 4 , - 2)
